J. WOOD PORTER, OF MORRIS, ILLINOIS.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,072, dated April17, 1883.

Application filed September 11, 1882. (No model.)

To all whom it may concern:

Be it known that I, J. W001) PORTER, a citizen of the United States,residing at Morris, in the county of Grundy and State of Illinois, haveinvented certain new and useful Improvements in Washing-Machines, ofwhich the following is a specification, reference being had to theaccompanying drawings, forming part hereof, in which- Figure 1 is a topplan view. Fig. 2 is the same view, the lid being turned to a verticalposition, showing the inside of the tub. Fig. 3 is a bottom view of therotary rubber; and Fig. 4 is a detail view, showing the manner ofattaching and securing the gear wheel by Willill the shaft of the rotaryrubber is actuate My invention relates to that class of washing-machines in which the clothes are cleansed by rotary rubbing betweenan upper and a lower surface suitably roughened and it consists incertain improvements in the construction and combination of the partscomposing a machine of that class, as will be first fully" describedhereinafter, and then particularly pointed out in the claims.

Referring to the drawings by letter, A is an ordinary wash-tub coveredby a stationary segment, B, and hinged lid 0. The bottom a. of the tubis provided with a number of projections, b, which consist of half-ovalblocks of wood or metal, attached to the bottom by means of screwspassing up through the bottom.

D is the rotary rubber, similarly provided with projections d. Securedto the center of and at right angles to the rubber D is a square shaft,E.

On top of the lid 0 is mounted the mechanism by which the rubber isrotated, which is constructed as follows: On an upright shaft or pin, F,which is secured to the lid by means of a washer or flange,f, above thelid, and a similar one, f, below the lid, is an ordinary gear-wheel, G.This gear-wheel is provided with loops g, into which a handle, H, issecured, and meshes with a gear, I, which is cast solid with its shaftJ, and that shaft is provided with a longitudinal rectangular per-'foration to receive the square shaft E of the rubber. Each end of theshaft J is cut down and the lower end is stepped in a socket in a plate,L, attached by any suitable means to the lower side of the lid 0. Theupper end of this shaft has a bearing in a socket in the lower side of astrap, K, which is secured to the top of the lid O by any suitablemeans. The plate L and strap K are each perforated with round openingsto permit the shaft E to pass through them and be revolved with the gearI.

The operation-of my device is as follows: The articles to be cleansedare placed in the tub, water being provided therein, and the lid, andwith it the rotary rubber, is brought down on them. The handle or leverH is now moved from side to side, causing the gear-wheel G toalternately rotate in opposite directions. This causes a similarrotation of the gear -I, which carries with it the shaft E and rubber D.The clothes are thus rubbed between two surfaces, each of which isprovided with halfoval projections, and are quickly and effectuallycleansed.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent, is

1. The combination, with the tub having oval projections on its bottom,of the rotary rubber having similar downward projections, andupward-projecting square shaft, the hinged lid, the socketed perforatedplate L, the shaft and pinion I J, perforated as described, the strap K,having socket and perforation, and suitable means foralternatel yrotating the shaft J, substantially as described.

2. The rotary rubber, its square shaft, the pinion and shaft I J, havingsquare opening to receive the square shaft, the plate L, provided withstep for shaft J, and the strap K, secured to the lid and having bearingfor the upper end of the shaft J, all constructed as described, andcombined with the hinged lid 0, as and for the purpose set forth.

3. The combination, substantially as described, of the lid 0, plate L,attached to its lower side, strap K, attached to its upper side, theplate and strap being perforated and socketed as described, the rubberhaving square shaft, the pinion and shaft I J, perforated to receivesaid square shaft, the gear-wheelG,

loops 9, and handle H, as and for the purpose set forth.
